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.
