4[x-3]+12=15-5[x+6]
Answers
4(x-3)+12=15-5(x+6)
One solution was found :
x = -5/3 = -1.667
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(x-3)+12-(15-5*(x+6))=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((4•(x-3))+12)-(15-5•(x+6)) = 0
Step 2 :
Equation at the end of step 2 :
(4 • (x - 3) + 12) - (-5x - 15) = 0
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
9x + 15 = 3 • (3x + 5)
Equation at the end of step 4 :
3 • (3x + 5) = 0
Step 5 :
Equations which are never true :
5.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
5.2 Solve : 3x+5 = 0
Subtract 5 from both sides of the equation :
3x = -5
Divide both sides of the equation by 3:
x = -5/3 = -1.667
One solution was found :
x = -5/3 = -1.667
please follow me and mark it as brainliest
4(x - 3) + 12 = 15 - 5(x + 6)
4x - 12 + 12 = 15 - 5x - 30
4x + 5x = 15 - 30 + 12 - 12
9x = -15
x = -15/9
