Answer:
x = −2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(−3x+4)+3x−3=−29
Step 1: Simplify both sides of the equation.
−2(−3x+4)+3x−3=−29
(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)
6x+−8+3x+−3=−29
(6x+3x)+(−8+−3)=−29(Combine Like Terms)
9x+−11=−29
9x−11=−29
Step 2: Add 11 to both sides.
9x−11+11=−29+11
9x=−18
Step 3: Divide both sides by 9.
9x
/9 = −18
/9
x=−2

Answer is b for this question
Answer:
-9
Step-by-step explanation:
2(-x)² - 5 = 157
2x² - 5 = 157
add 5 to each side of the equation:
2x² = 162
divide both sides by 2:
x² = 81
√81 = 9 or -9
Answer:
x = 6
Step-by-step explanation:
1/2(18-5x)=1/3(6-4x)
9 - 5/2x = 2 - 4/3x
7 = 7/6x
x = 6
