Answer:
x = 125/74
x = 1.68918919.....
Step-by-step explanation:
To solve for "x", simplify each side. Then, move "x" to the left, and move other numbers to the right. When moving something, do the reverse operation to both sides of the equation. Do reverse operations in reverse BEDMAS order.
8x − 10 − 4x = −12(12x − 20) Collect like terms on left side
4x − 10 = −12(12x − 20) Expand over brackets on right side
4x − 10 = −144x + 240
Start isolating "x" to the left side.
4x − 10 + 10 = −144x + 240 + 10 Add 10 to both sides
4x = −144x + 250
4x + 144x = −144x + 250 + 144x Add 144x to both sides
148x = 250
148x/148 = 250/148 Divide both sides by 148
x = 250/148 Reduce the fraction by a factor of 2
x = 125/74 Final answer as a fraction
x = 1.68918919..... Final answer as an unrounded decimal
