4x+10+3x+23=180 combine all like terms 4x+3x=7x 10+23=33 rewrite
7x+33=180 subtract 33 from both sides 147 rewrite 7x=147 divide 7 from
both sides which is 21 x=21
To find y 3x+23+y=180 plug 21 in for x
rewrite 3(21)+23+y=180 3(21)=63 rewrite 63+23+y=180 combine like terms
63+23=86 rewrite 86+y=180 subtract 86 from both sides 94 y=94
X=21 and Y=94
Hope this helps have a nice day
