3.6 is the solution of equation 2.8 + x = 6.4______ (judge right or wrong)

3.6 is the solution of equation 2.8 + x = 6.4______ (judge right or wrong)

2.8 + x = 6.4, 2.8 + x-2.8 = 6.4-2.8, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 3.6, so the answer is: correct

In 4 × 2 = 8, 6 + X ＜ 20, X △ 6 = 2, X-10 = 4, 4 5 = 8x, the equation has (), the equation has（

1,3,4,5 are equations
3, 4 and 5 are equations
An equation representing the equality of two numbers or two algebraic expressions is called an equality. Two numbers or two algebraic expressions are connected by an equal sign "=". For example: 27 + 23 = 50, a + B = B + A, 4x + 6 = 86
Equation "is also called" equation "or" system of equations ", that is, the equation containing unknowns. For example: X-2 = 5, x + 8 = Y-3

In 4,20,6 and 1 / 2,1.8, () is the solution of equation 1 / 2 + X, () is the solution of equation 30% x = 6

(20) is the solution of equation 30% x = 6
It's not an equation

Solve the following equation X-8 = 16 5x = 80 43-x = 38 20-x = 9 6.31 △ x = 7 x △ 4
Solve the following equation
x-8=16
5x=80
43-x=38
20-x=9
6.31÷x=7
x÷4.5=1.2

X－8＝16
X＝24
5x＝80
x＝80÷5
X＝16
43－X＝38
X＝5
20-x＝9
X＝11
6.31÷x＝7
X≈0.9
X÷4.5＝1.2
X＝5.4
