Question

equaçao de 1gral como resolver? 5×=35 5×=×+16 4×=12+× 3×=21 6×=24+3 2×+3=×+4 5×+7=4×+10 me ajudem por favor​

Answer 1

$5x = 35 \\ x = \frac{35}{5} \\ x = 7$

----------------------

$5x = x + 16 \\ 5x - x = 16 \\ 4x = 16 \\ x = \frac{16}{4} \\ x = 4$

----------------------

$4x = 12 + x \\ 4x - x = 12 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$

----------------------

$3x = 21 \\ x = \frac{21}{3} \\ x = 7$

----------------------

$6x = 24 + 3 \\ 6x = 27 \\ x = \frac{9}{2} \: \: {}^{( \div \: 6)}$

----------------------

$2x + 3 = x + 4 \\ 2x - x = 4 - 3 \\ x = 4 - 3 \\ x = 1$

----------------------

$5x + 7 = 4x + 10 \\ 5x - 4x = 10 - 7 \\ x = 10 - 7 \\ x = 3$
