System of equations
2x+4y=8
X=3y-6

Answers

Answer 1

Answer: 2x + 4y = 8
x = 3y - 6

2x + 4y = 8
2 * ( 3y - 6 ) + 4y = 8
6y + 12 + 4y = 8
8y = 8 - 12
8y = - 4
y = -4 / 8
y = -1 / 2

What is the largest value of x that is not a solution to:
-(9x-4)+12+18x>79

Answers

Answer:

7

Step-by-step explanation:

given the expression, we are expected to solve for the value of x

$-(9x-4)+12+18x>79$

we begin by opening the bracket

$-(9x-4)+12+18x>79\n\n-9x+4+12+18x>79\n\n$

collect like terms

$-9x+4+12+18x>79\n\n-9x+18x+4+12>79\n\n9x+16>79\n\n$

subtract 16 from both sides

$9x+16>79\n\n9x>79-16\n\n9x>63$

divide both sides by 9 we have

$x>(63)/(9)\n\n x>7$

the greatest value of x that is not a solution is 7 since x is not equal to 7
