Question

solve 8x-27=28 and x+4y=-5​

Answer 1

${\bigstar}$ SOLUTION:

➤8x-27=28

➤8x = 28+27

➤8x = 55

➤x = $\frac{55}{8}$

sub/: x = $\frac{</strong><strong>5</strong><strong>5</strong><strong>}{8}$in second equation ,

☞x+4y=-5

☞$( \frac{55}{8} )$+4y = -5

☞4y = -5 - $( \frac{55}{8} )$

☞4y = $\frac{(8)5 - 55}{8}$

☞4y × 8 = -40-55

☞32y = -95

☞y = $\frac{-95}{32}$

Answer 2

8x-27=28

=>8x=28+27

=>x=55/8

x+4y=-5

=>55/8+4y=-5

=>4y=-5-55/8

=>y=--95/8÷4

=>y=-95/8×1/4

=>y=95/32

hope it helps
