Answer:
4(3x-10)
Step-by-step explanation:
12x-40 = (4*3)x-(4*10) = 4(3x-10). The GCF is 4.
Answer:
-3 -3x
Step-by-step explanation:
12−3∙(5+x)
simplify
12 - 3(5) + -3(x)
12 - 15 - 3x
-3 - 3x
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
