Solve for x: 5x+3+8x-4=90

aleksley [76]

Answer:

$x = 7$

Step-by-step explanation:

We can solve the equation $5x+3+8x-4=90$ by isolating the variable x on one side. To do this, we must simplify the equation.

$5x+3+8x-4=90$

Combine like terms:

$13x - 1 = 90$

Add 1 to both sides:

$13x = 91$

Divide both sides by 13:

$x = 7$

Hope this helped!

What is the product of (3x - 4y) and (- 2x + 5y - 6)?

guajiro [1.7K]

Answer:

The answer is option c

Step-by-step explanation:

Product means we have to multiply

$(3x - 4y) \times ( - 2x + 5y - 6) \\ 3x( - 2x + 5y - 6) - 4y( - 2x + 5y - 6) \\ - 6x {}^{2} + 15xy - 18x + 8xy - 20y { }^{2} + 24$

You then group like terms

$- 6x {}^{2} + 15xy + 18xy - 20y {}^{2} + 24 \\ 6x {}^{2} + 23xy - 20y {}^{2} + 24$

And there's your answer

Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a
