Answer:
see explanation
Step-by-step explanation:
Given
3x - y = 2
Substitute y = x - 1 into the equation
3x - (x - 1) = 2
3x - x + 1 = 2 ← simplify left side
2x + 1 = 2 ← required equation after substitution
Answer:
814 coz when you add these number you got 814
Answer= 2/3
5 2/3= multiply 5x3=15, then 5x2=10 which makes the fraction: 10/15, simplify by finding the highest common denominator that divides 10 & 15 equally, which would be 5,
5 divided into 10 is 2. 5 devided into 15 is 3 which makes your answer, 2/3.
not 100%, but it makes sense to me...
First you graph "y = 2x +2." You shade in the region below it, because it's y "LESS THAN" and you keep the line solid (not dotted) because it's "equal to" 2x+2 too.
