Answer: x = -135.59
Step-by-step explanation:
20 = 0.694(x + 150)(2)
Step 1: Simplify both sides of the equation.
20 = 0.694 (x + 150)(2)
20 = 1.388x + 208.2 (use the distributive property)
20 = 1.388x + 208.2
Step 2: Flip the equation.
1.388x + 208.2 = 20
Step 3: Subtract 208.2 from both sides of the equation.
1.388x + 208.2 − 208.2 = 20 − 208.2
1.388x = −188.2
Step 4: Divide both sides by 1.388.
1.388x/1.388 = −188.2/1.388
x = −135.590778
Optional: Simplify
x = -135.59
