Question

Solve each pair of simultaneous equations by substitution method​

Answer 1

x = 6 and y = 4

Explanation:

Just substitute the lower equation into the top one.

Answer 2

x = 6 and y = 4

Explanation:

Let's substitute x = y + 2 into 3x + 2y = 26.

3(y + 2) + 2y = 26

3y + 6 + 2y = 26

5y + 6 = 26

-6 -6

-------------------------

5y = 20

/5 /5

-------------------------

y = 4

Now, we know y = 4. We can plug y = 4 in either x = y + 2 or 3x + 2y = 26 to find the x value. Let's do x = y + 2.

x = 4 + 2

x = 6

Thus, x = 6 and y = 4
