Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = −

Due to m<2 is a corresponding angle to m<6, the answer to the question is 146°.
Answer:
12
Step-by-step explanation:
8.x-13=3+4.x
8.x-13=7.x
x-13+8=7.x
x-5=7.x
x-x=7+5
x-x=12
x=12
In the first step when the student did -2x-3 they didn’t make the sign positive. It should be 4=-2+6, not 4=-2-6
x^2 =144 has 2 solutions
x=sqrt(144)
x=+-12
x= 12 and x=-12
12*12 = 144 and (-12) * (-12) = 144
a square root has 1 positive and 1 negative solution
x^3 = 27
(x^3)^(1/3)=(27)^(1/3) ^(1/3) is the cube root
x = 3
it only has one solution because a negative * a negative * a negative would be negative
