Answer: 12=7−3x+5x
Step 1: Simplify both sides of the equation.
12=7−3x+5x
12=7+−3x+5x
12=(−3x+5x)+(7)(Combine Like Terms)
12=2x+7
12=2x+7
Step 2: Flip the equation.
2x+7=12
Step 3: Subtract 7 from both sides.
2x+7−7=12−7
2x=5
Step 4: Divide both sides by 2.

Answer:
b.) y=-x-3
Step-by-step explanation:
Your slope is negative 1 and the y intercept is -3.
Complementary angles add to 90 degrees.
3x+5+2x-15=90
5x-10=90
5x=100
x=20 <=======
Plug in the value of x
3(20)+5
60+5
65= angle A <========
2(20)-15
40-15
25= angle B <========
