Objective: Students will be able to ______an algebraic expression by applying the ______.
QUICK REVIEW: COMBINING LIKE TERMSMr. Johnson stops at a fruit stand and buys 2 apples, 3 bananas, and a grapefruit. If he stops at another stand and buys an apple, 2 bananas, and 3 grapefruits, how many of each fruit would he have? Write as a simplified algebraic expression. / QUICK REVIEW: DISTRIBUTIVE PROPERTY
2 ( X + 3)
-3 (X – Y)
1)We try:
DISTRIBUTING AND COMBINING
4 (x + y) – (x + 2) / 2)You try:
DISTRIBUTING AND COMBINING
-2( x + y) + 2x + -3y
3)We try:
y (2 + y) + 3y / 4)You try:
x (x – 4x) + 6x
5)We try:
3 (2x + 4) – x( x – 5) / 6)You try:
2b(3 – b) – 7(2 +3b)
7)We try:
x( 2x + 3) + 2(x + y) + 10 / 8)You try:
-4a(a – 2) + 3(2a + 3)
- SIMPLIFY THE EXPRESSION
b – 2a / 2. SIMPLIFY THE EXPRESSION
2(x – y) + 2y + 3x
5x / 3. Solve The equation
4x - 3 = 45
X = 12
4. Solve The equation
2a + 3a = 10
a = 2 / 5. SIMPLIFY THE EXPRESSION
7 ( x + 3) – 12 + 4x
11x + 9 / 6. Solve The equation
6x = -36
X = -6
7. SIMPLIFY THE EXPRESSION
8x + 3( x + y) + 12y
11x + 15y / 8. SIMPLIFY THE EXPRESSION
X(7 +2x) + 10(x – y) + 3y
2x2 + 17x – 7y / 9. SIMPLIFY THE EXPRESSION
4(x + y) + x( 2x + 3y) – 15x
2x2 – 11x + 4y + 3xy
10. SIMPLIFY THE EXPRESSION
10a + 3a( 2a + 4) + 12 – (4 + a)
6a2 + 21a + 8 / 11. SIMPLIFY THE EXPRESSION
4( x + y) – 12(2 – x) + 17y
5x + 21y - 24 / 12. SIMPLIFY THE EXPRESSION
10 (c + 2b) + 12 + 7(b + 10)
27b + 10c + 82
13. SIMPLIFY THE EXPRESSION
x + 2(x + 5) - 6x
-3x + 10 / 14. SIMPLIFY THE EXPRESSION
a(3 + 2a) + 4(2 + 2a) – 5a
2a2 + 6a + 8 / 15. Solve The equation
-9 + x – 8 = 34
X = 51
