solve the following equation and check the equation 5-3(5x+2)=4(7-3x)+1
Answers
Step-by-step explanation:
Simplifying
5 + -3(5x + 2) = 4(7 + -3x) + 1
Reorder the terms:
5 + -3(2 + 5x) = 4(7 + -3x) + 1
5 + (2 * -3 + 5x * -3) = 4(7 + -3x) + 1
5 + (-6 + -15x) = 4(7 + -3x) + 1
Combine like terms: 5 + -6 = -1
-1 + -15x = 4(7 + -3x) + 1
-1 + -15x = (7 * 4 + -3x * 4) + 1
-1 + -15x = (28 + -12x) + 1
Reorder the terms:
-1 + -15x = 28 + 1 + -12x
Combine like terms: 28 + 1 = 29
-1 + -15x = 29 + -12x
Solving
-1 + -15x = 29 + -12x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12x' to each side of the equation.
-1 + -15x + 12x = 29 + -12x + 12x
Combine like terms: -15x + 12x = -3x
-1 + -3x = 29 + -12x + 12x
Combine like terms: -12x + 12x = 0
-1 + -3x = 29 + 0
-1 + -3x = 29
Add '1' to each side of the equation.
-1 + 1 + -3x = 29 + 1
Combine like terms: -1 + 1 = 0
0 + -3x = 29 + 1
-3x = 29 + 1
Combine like terms: 29 + 1 = 30
-3x = 30
Divide each side by '-3'.
x = -10
Simplifying
x = -10
