Answer:
y=3, x=2
Step-by-step explanation:
-3x-2(5x-7)=-12 (substitute y=5x-7)
simplify
{-13x+14=-12\}
isolate x for -13x +14=-12: x=2
for y=5x-7 substitute x=2
simplify y=3
sorry i know this is quite lenghty but i hope this helps :) have a nice day !!

Answer: The slope is 5/4 and the y intercept will be 2
Step-by-step explanation:
First convert the equation to slope intercept form ( y = mx+b) where m will be the slope and b will be the y intercept.
5x - 4y = -8 Subtract 5x from both sides
-5x -5x
-4y = -5x - 8 Divide both sides by -5
y = 5/4x + 2
1/7-11/2:(3×2+5)/4-(2-1×7)/7
= 1/7-11/2: 11/4 +5/7
= 1/7-11/2 ×4/11 +5/7
=1/7 -2 +5/7
=(1 -2×7 + 5)/7
=(1-14+5)/7
=-8/7➡ANS
❇NOTE:
↪Same rule is applied here like in the question before....
▶solve ( ) bracket first
▶ : means ratio sign and is same as / sign
▶DMAS rule is followed throughout the question
▶11/2: 11/4=11/2× 4/11 ...here ratio sign can be converted into Multiplication sign by reciprocating the term after : sign
