Answer:
z/2 + 1 = x
Step-by-step explanation:
z=2(x-1)
z/2 = x-1
z/2 + 1 = x
B. y=12x+7
Explanation
The slope is 12; slope=m
The yint is 7; yint=b
The equation of a line is set up as so
y=mx+b
Now we just need to replace the variables with the numbers
y=12x+7
Answer:
See explanations below
Step-by-step explanation:
Given the system of equation
2x - 10 y = -30 ... 1
x - 5y = 20 ... 2
Step: From 2;
x = 20 + 5y ...3
Step 2: Substitute equation 3 into 1
2x - 10y = -30
2(5y+20) - 10y = -30
Open the bracket
10y + 40 - 10y = -30
10y - 10y + 40 = -30
0+40 = -30
40 = -30
