Answer:
Step-by-step explanation:
This is another method you could use.
PEMDAS
parentheses, exponent, multiplication/division, addition/subtraction
first, start with what is inside the parentheses that is solvable.
5(6) - (x-3) = -4(4x+5) + 13
multiply what you can
30 - (x-3) = -16x - 20 + 13
simplify
30 - (x-3) = -16x - 7
subtract 30 on both sides
- (x-3) = -16x - 37
let’s separate -(x-3).
-x - 3 = -16x - 37
add 16x to both sides
15x - 3 = -37
add 3 to both sides
15x = -34
x = -34/15 or -2.2667
