Question

2(3x - 7) + 4(3x + 2) = 6(5x + 9)

Answer 1

6х-14+12х+8=30х+54
6х+12х-30х=54+14-8
-12х=60
х=-5

Answer 2

2(3х-7)+4(3х+2)=6(5х+9)
6х-14+12х+8=30х+54;
18х-6=30х+54;
18х-30х=54+6;
-12х=60;
х= -5;
Ответ : -5.

Answer 3

Let's solve the given equation step by step:

2(3x - 7) + 4(3x + 2) = 6(5x + 9)

Step 1: Distribute the values inside the parentheses: 2 * 3x - 2 * 7 + 4 * 3x + 4 * 2 = 6 * 5x + 6 * 9

Step 2: Simplify the expressions on both sides: 6x - 14 + 12x + 8 = 30x + 54

Step 3: Combine like terms on both sides: (6x + 12x) + (-14 + 8) = 30x + 54

Step 4: Further simplify the expressions: 18x - 6 = 30x + 54

Step 5: Move the variable terms (with x) to one side and the constant terms to the other side: 18x - 30x = 54 + 6

Step 6: Combine like terms: -12x = 60

Step 7: Divide both sides by -12 to solve for x: x = 60 / -12 x = -5

So, the solution to the equation is x = -5.
