Complete the solution of the equation. Find the value of [tex]y[/tex] when [tex]x = -10[/tex].

[tex]
2x - 9y = -38
[/tex]


Sagot :

Certainly! Let's solve the given equation for [tex]\( y \)[/tex] step-by-step when the value of [tex]\( x \)[/tex] is [tex]\(-10\)[/tex].

The given equation is:
[tex]\[ 2x - 9y = -38 \][/tex]

1. Substitute [tex]\( x = -10 \)[/tex] into the equation:

[tex]\[ 2(-10) - 9y = -38 \][/tex]

2. Simplify the equation:

[tex]\[ -20 - 9y = -38 \][/tex]

3. Isolate the term involving [tex]\( y \)[/tex]:

Add 20 to both sides of the equation to move the constant term to the right side:

[tex]\[ -9y = -38 + 20 \][/tex]

Simplify the right side:

[tex]\[ -9y = -18 \][/tex]

4. Solve for [tex]\( y \)[/tex]:

Divide both sides of the equation by [tex]\(-9\)[/tex]:

[tex]\[ y = \frac{-18}{-9} \][/tex]

Simplify the fraction:

[tex]\[ y = 2 \][/tex]

Therefore, the value of [tex]\( y \)[/tex] when [tex]\( x = -10 \)[/tex] is:

[tex]\[ y = 2 \][/tex]
