Answer:

(0.4, 5.2)

Step-by-step explanation:

Wherever you see a y in the first equation, put in 3x + 4

2x + 3x + 4 = 6        Combine like terms

5x + 4 = 6                 Subtract 4 from both sides

5x + 4 - 4 = 6 - 4      Combine like terms.

5x = 2                       Divide both sides by 5

5x/5 = 2/5                Do the division

x = 0.4                      

====================

Solve for y

y = 3x + 4

y = 3*0.4 + 4

y = 1.2 + 4

y = 5.2

Solution

(0.4 ,  5.2)
