Answer:
x=-26
Step-by-step explanation:
Subtract 45 from both sides.
-85-45=5x
Simplify -85-45 to -130
-130=5x
Divide both sides by 5.
-130/5=x
Simplify 130/5 to 26
-26=x
Answer:
12a + 18 = 12a + 18
Step-by-step explanation:
times what's in the brackets by what's to the left of the brackets
6x + 3y = 79.5
3x + 2y = 41 y = -3/2x + 41/2 y = -1.5x + 20.5
6x + 3(-1.5x + 20.5) = 79.5
6x - 4.5x + 61.5 = 79.5
1.5x + 61.5 = 79.5
1.5x = 18
x = 12
Each shirt costs $12.
Now insert that number into the x to find the cost of each tie.
3(12) + 2y = 41
36 + 2y = 41
2y = 5
y = 2.5
Each tie costs $2.50.
