X1=4x5 I think it is. Though this would then give x=20x with I think is impossible...

Solve by substitution 3x+y=5 and 2x-y=10

prohojiy [21]

3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15

3(-15)+y=5
-45+y=5
+45 +45
y=50

2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40

Find the values of x and y. Show your work.

Ira Lisetskai [31]

7x-4=31
7x=31+4
7x=35
x=35/7=5

4y+8=24
4y=24-8
4y=16
y=16/4=4

Hence, x=5;y=4

Solve: | 2x - 2 | = x + 1

Evgesh-ka [11]

The given expression is $|2 x-2|=x+1$

We need to determine the solution to the expression.

<u>Solution:</u>

The absolute value of the expression $|2 x-2|=x+1$ is given by

$2 x-2=x+1$ or $2 x-2=-(x+1)$

Let us solve the expression $2 x-2=x+1$

Thus, we get;

$x-2=1$

$x=3$

Now, solving the expression $2 x-2=-(x+1)$

Thus, we get;

$2x-2=-x-1$

$3x-2=-1$

$3x=1$

$x=\frac{1}{3}$

Thus, the solution of the expression is $x=3$ , $x=\frac{1}{3}$

Hence, Option B is the correct answer.
