−2(−3x+4)+3x−3=−29 what does x equal
gogolik [260]

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

I hope this helps!!!

What is the solution to the given system of equations?<br><br> y=4x-3<br><br> y=-x-13
Paraphin [41]
4x - 3 = -x - 13
4x + x = -13 + 3
5x = -10
x = -10/5
x = -2

y = 4x - 3
y = 4(-2) - 3
y = -8 - 3
y = -11

solution is (-2,-11)
