Step-by-step explanation:
Do distributive property then add like terms.
6x-10+6x+9
12x-1
Answer:
72,012,044
Step-by-step explanation:
If you can't figure this out, your calculator can help:
72×1,000,000 +12×1,000 +44 = 72,012,044
Step-by-step explanation:
Equation 1
Equation 2
Answer:
(2,2)
Step-by-step explanation:
Given equations
x-3y=-4-------------------------------(1)
y=-3x+8.------------------------------(2)
Substitute 2 in 1. This means use the value of y in equation 1, to replace y
x-3(-3x+8)=-4------------------open brackets
x+9x-24=-4---------------------collect like terms
10x=-4+24
10x=20---------------------------divide by 10 both sides to get value of x
10x/10=20/10=2
x=2------------------------------use value of x in equation (2) to get value of y
y=-3x+8
y=-3(2)+8
y=-6+8=2
solutions
x=2, y=2
