Answer:
Step-by-step explanation:
(x+1 = whatever the letter x represents the multiply it to 4 then do 2. - 3= -1 x 5= 4 + the sum of 1 and x times 4. Hope it helps <3

Solutions
There are three methods to solve this problem :-
<span>Substitution
</span>
<span>Elimination
</span>
<span>Matrix
</span>
To solve this problem we will use substitution.
Calculations
⇒ Lets solve for the variable x in x+3y=5
→ x+3y = 5
⊄ Subtract 3y from both sides ⊅<span>
</span>→ <span>x = 5−3y
</span>Substitute <span><span>x=5−</span>3y</span> into <span>x−3y =−1
</span>⇒ Start with the original equation<span>
</span><span>x−3y=−1
</span>
⇒ Let <span>x=5−3y
</span><span>5−3y−3y=−1
</span>
⇒ <span>Simplify
</span><span>5−6y=−1
</span>Solve for y<span> in </span><span>5−6y=−<span>1
</span></span><span>y=1
</span>
Substitute <span>y=1</span><span> into </span><span>x=5−3y
</span><span>x=2
</span>Therefore,
<span><span>x=2
</span></span><span><span>y=1</span></span><span>
