Question

2x+10+2x+2y=180 2x+3y+2y-5=180 find the x and y​

Answer 1

Answer:

X = 30

Y= 25

Step-by-step explanation:

$2x + 10 + 2x + 2y = 180$

$4x + 2y = 180 - 10$

$4x + 2y = 170 \: (equation \: 1)$

$2x + 3y + 2y - 5 = 180$

$2x + 5y = 180 + 5$

$2x + 5y = 185 \: (equation \: 2)$

$(2(equation \: 2)) - equation \: 1$

$(2(2x + 5y = 185)) - (4x + 2y = 170)$

$(4x + 10y = 370) - (4x + 2y = 170)$

$10y - 2y = 370 - 170$

$8y = 200$

$y = 200 \div 8 = 25$

If y = 25 then giving Y in equation 1

$4x + 2y = 170$

$4x + 50 = 170$

$4x = 170 - 50 = 120$

$x = 120 \div 4 = 30$

$x = 30$

$y = 25$
