Example 1
Step 3:
After substituting the first equation into the second one and working it out, I got
x = 1.
What should I do next? Then do it.
Fill in 1 for x in y = 6x
y = 6(1)
y = 6
Fill in 1 for y in y = 6x
1 = 6x
1/6 = x
Fill in 1 for y in 2x + 5y = 32
2x + 5(1) = 32
2x + 5 = 32
2x = 27
x = 27/2

In step 1, we got x = y. Which shows the correct steps for step 2 (substituting and solving)?
18x + 2y = 0
18(y) + 2y = 0
20y = 0
No Solution
18x + 2y = 0
18(y) + 2y = 0
20y = 0
y = 0

Which statement is correct to begin to solve this equation?
The variable is already isolated in the first equation, so we have already solved it.
The variable is already isolated in the first equation, so we have to plug into the second one like this:
-4(4-2x) - 2y = -8
The variable is already isolated in the first equation, so we have to plug into the second one like this:
-4x - 2(4 - 2x) = -8

MULTIPLE CHOICE QUESTION

Example 3: y = 4 - 2x -4x - 2y = -8 Finish step 2 (which shows correct steps): -4x - 2(4 - 2x) = -8
-4x - 2(4 - 2x) = -8
-4x - 8 + 4x = -8
8 = -8
-4x - 2(4 - 2x) = -8
-4x - 8 - 4x = -8
-8x - 8 = -8
-8x = 0
x = 0
-4x - 2(4 - 2x) = -8
-4x - 8 + 4x = -8
-8 = -8
-4x - 2(4 - 2x) = -8
-4x - 8 - 2x = -8
-6x - 8 = -8
-6x = 0
x = 0
