-4(-1.5 - 9)
-4 x -1.5 = 6
-4 x 9 = -36
Answer is -30
Answer:
16m
Step-by-step explanation:
4 x 2 = 8
8 x 2 = 16
Answer:
x = -2
Step-by-step explanation:
-9x + 1 = -x + 17
To solve this equation
Note if there is more than one variable like x, y, or z
Also note the power of the variables, for example, x^2 or y^3
In this equation, there is only one variable which is x and it's also in the power of 1 ie x
Step 1 : rearrange according to like terms
-9x + x = 17 - 1
( don't forget that the sign always change on crossing an equals to, either + to - or - to +
-9x + x (also means 9 - 1 but only carries a negative sign)
= - 8x = 16
Dividing both sides by -8 to get the value of x
-8x / 8 = 16 /- 8
x = 16/ -8
x = -2
<em>x₁ = 5</em>
<em>x₂ = - 2</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>x² - 3x - 10 = 0</em>
<em>x² + 2x - 5x - 10 = 0</em>
<em>x(x + 2) - 5(x + 2) = 0</em>
<em>(x - 5)(x + 2) = 0</em>
<em>x - 5 = 0 => x₁ = 5</em>
<em>x + 2 = 0 => x₂ = - 2</em>
<em>Good luck !</em>
