Answer:
Explanation:
9x+3y=420 ---------- (eq1)
1x+6y=296 -----------(eq2)
to solve by elimination, we first multiply (eq 1) by 2
(eq1) x 2
2(9x+3y)=2 (420)
18x + 6y = 840 -----(eq 3)
eliminate y term by subtracting (eq2) from (eq3)
(eq 3) - (eq 2)
(18x + 6y) - (1x+6y) = 840 - 296
18x + 6y - 1x-6y = 544
18x - 1x = 544
17x = 544 (divide both sides by 17)
x = 544/17 = 32
Since you said that you are not looking for the answer, i will stop here, but to get the y value, subtitute the value of x which we found, back into eq 1 or 2 to find y
